Plugin #3:

Display a “teaser” widget in your website’s sidebar with posts/ pages from any membership level you choose, so when visitors will click on any of the links inside the widget to see the content, they will be redirected to an error page.

Inside the error page you can sell them your membership more easily, because obviously they were interested enough to click on the link…, and you will increase the registrations to your membership site significantly.
